We can't decide if the Glow in the Dark Moon clock makes a room look more romantic or like science nerd central. Two very different concepts. We do think it's a cool piece of art for the wall. The face is an image mash-up of 65 different actual photographs of the moon. A round domed glass front is a nice detail. The clock face glows for 2 hours after lights are off. Powered by 1 AA battery. Sweep hands technology which means no ticking sounds. 15 hours of daylight equals 4 hours of illumination. Requires 1 AA battery (not included).
